研究了修理工有多重休假的三部件串一并联可修系统的可靠性,在假定部件1的寿命服从参数为λ0(λ0〉0)的指数分布,部件2、3的寿命服从参数为λ1(λ1〉0)的指数分布条件下,利用密度演化方法,得到了系统的瞬时可用度和稳态可用度、系统的可靠度、修理工休假和系统等待修理的概率等一些重要的可靠性结果.
This paper considers the reliability of the repairable system of three units-series-parallel connection with a repairman multiple vocations. Suppose that the life length of the unit 1 has exponential distribution with parameter λ0 (λ0 〉 0), the life length of the unit 2 and unit 3 has exponential distribution with parameter λ1 ( λ1 〉 0) , by using the method of density evolution, we discuss the point-wise availability and the stead-state availability of the system, the reliability of the system, the repairman' s vocation probability and the probability of waiting for repairs. Some important reliability of the results are obtained.
